Phys. Rev. B 54, 2931–2936 (1996)Kinetics of nucleation-dominated step flowReceived 28 September 1995; published in the issue dated 15 July 1996 On some surfaces, preferential growth takes place at the step edges, because these act as heterogeneous nucleation sites for adatoms to come together. In this paper, we present a one-dimensional theory for the steady-state kinetics of step flow, under conditions of both growth and evaporation, explicitly taking this growth mechanism into account. The growth properties such as step velocities are examined as a function of external flux and terrace width. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
